Description

Technical Field

[0001] The utility model belongs to the field of medical instruments, and in particular relates to a limiting and fixing device for emergency treatment of limb injuries. Background Art

[0002] Limb trauma refers to conditions such as limb fractures, joint dislocations, and soft tissue contusions, usually caused by traffic accidents, industrial accidents, or sports injuries. These injuries may cause severe pain, dysfunction, and other complications, so timely first aid and proper fixation are crucial. At present, first aid treatment for limb trauma mainly includes hemostasis, fixation, and transportation. Fixation is a key step. The limited fixation device can stabilize the injured part, relieve pain, prevent further damage, and provide support for subsequent treatment and rehabilitation.

[0003] However, traditional fixation devices usually have some shortcomings. For example, traditional plaster fixation requires professional doctors to operate, which is time-consuming and laborious; and after plaster fixation, puncture inspection or dressing change cannot be performed, making injury observation and treatment inconvenient; splint fixation requires professional medical staff to perform fast and effective fixation, which is relatively high, and splints are all of a unified standard, which is quite restrictive, and after fixing the injured part, it will limit the movement of the remaining joints.

[0004] In summary, the problems existing in the prior art are:

[0005] 1. The existing limiting and fixing devices for emergency treatment of limb trauma have relatively high technical requirements and require professional doctors to operate. They are not suitable for ordinary people and may cause ordinary people to delay time or improper operation when using them, affecting treatment;

[0006] 2. The existing limiting fixing devices for emergency treatment of limb injuries are all fixed devices of uniform size, which can fix the injured part and restrict the movement of other joints;

[0007] 3. The existing limiting and fixing devices for emergency treatment of limb injuries will hinder doctors from performing puncture inspections on the injured parts and changing dressings in subsequent treatments. Utility Model Content

[0008] The utility model relates to a limiting fixing device for emergency treatment of limb trauma. The fixing clamp flaps of the injured part can be fixed by setting an adjusting bolt. When changing the dressing or checking is needed, the fixing clamp flaps can be opened by operating the adjusting bolt. Moreover, the fixing clamp flaps are set as assembled clamp flaps to ensure that small-area injuries are accurately clamped and fixed without affecting the patient's movement.
